On Thursday 30 July 2026, voters across Greater Manchester took part in the largest by-election Britain has ever seen. More than two million people living in the ten boroughs of Bolton, Bury, Manchester, Oldham, Rochdale, Salford, Stockport, Tameside, Trafford and Wigan were eligible to choose a new mayor for the city region. The contest was not a routine election. It was forced by a dramatic chain of political events that began when Andy Burnham, the man who had defined the role since its creation, left the post after nearly a decade in office.
Burnham first won the mayoralty in 2017 and was re-elected in 2021 and 2024, building a reputation as one of the most recognisable and popular regional leaders in the country. In June 2026 he returned to Parliament by winning the Makerfield by-election. Because the Greater Manchester mayor also carries the powers of a police and crime commissioner, the law automatically disqualified him from continuing in the role once he became an MP. The vacancy was declared, Paul Dennett stepped in as acting mayor, and a by-election was arranged for 30 July. The winner will serve only until the next full election in 2028, completing the remainder of the current term.
The scale of the contest was unprecedented. Organisers estimated the cost at several million pounds. Polling stations opened at 7am and closed at 10pm on 30 July. Counting began the following morning, with a declaration expected later on 31 July. For the first time since the mayoralty was created, Burnham’s name was absent from the ballot paper.
The Voting System Explained
This election used the Supplementary Vote system. Each voter could mark a first-choice candidate and, if they wished, a second preference. If any candidate secured more than half of the first-preference votes, they were elected immediately. If no one reached that threshold, every candidate except the top two was eliminated. Second preferences from the eliminated ballots were then transferred to the remaining pair, and the candidate with the higher combined total became mayor.
The system had been used in the earlier Greater Manchester contests but was replaced by first-past-the-post for the 2024 election. It was restored for the 2026 by-election. Supporters argue that it gives voters a clearer voice and reduces the risk of a candidate winning on a relatively low share of the vote. Critics have sometimes pointed to complexity and the number of ballot papers that end up without a transferable second preference. In practice, most observers expected the race to go to a second round.
The Candidates and Their Platforms
Seven people stood for the post. Bev Craig, the Labour and Co-operative candidate, entered the contest as the clear favourite. As leader of Manchester City Council since 2021 and a senior figure on the Greater Manchester Combined Authority with responsibility for economy, business and inclusive growth, she presented herself as the continuity candidate. She spoke of building on previous progress in public transport, housing delivery, job creation and neighbourhood improvement. Her message centred on practical delivery rather than radical change.
Sian Astley stood for Reform UK. As leader of her party’s group on Manchester City Council, she sought to capitalise on the gains Reform had made in the local elections earlier in the year. Her campaign focused on tighter control of public spending, stronger community safety measures and a more sceptical approach to large-scale regeneration projects that some residents felt had left outer areas behind.
Geraldine Coggins represented the Green Party. A Trafford councillor, she benefited from the strong performance her party recorded in the May 2026 local elections, particularly in parts of Manchester. The Greens emphasised climate action, more ambitious affordable housing targets, better public transport and protection of green spaces.
Phil Eckersley stood for the Conservatives. A Trafford councillor, he argued for a focus on economic growth, support for local businesses and a more cautious approach to public expenditure. Richard Kilpatrick represented the Liberal Democrats, stressing community politics, local services and pragmatic solutions. Marlon West stood for Restore Britain, highlighting issues of community safety and social cohesion. Marcus Farmer, an independent who had previously contested the mayoralty, offered a non-party alternative.
The Campaign Atmosphere
The short campaign was shaped by the national political context. Burnham’s rapid rise from regional mayor to senior national figure cast a long shadow. Many voters still associated the mayoralty with his style of leadership. At the same time, the local elections of May 2026 had already shown shifts in support. Labour lost ground in several areas, while the Greens and Reform made noticeable advances. Housing emerged as a dominant theme. Candidates debated the tension between rapid city-centre development and the need for genuinely affordable homes in every borough. Transport, particularly the continued expansion and integration of the Bee Network, remained a central talking point. Crime, anti-social behaviour and the quality of local high streets also featured heavily.
Opinion surveys conducted in the weeks before polling day consistently placed Craig ahead on first preferences, usually in the mid-to-high thirties. Reform and the Greens competed for second place, with Reform often slightly ahead. The Conservatives trailed further back. Most projections suggested that even if the contest went to a second round, Craig would defeat either of her main rivals by a clear margin. The figures indicated a significant drop from the large majorities Burnham had enjoyed, reflecting both the absence of his personal brand and the broader political currents visible earlier in the year.
What the Mayor Actually Does
The Mayor of Greater Manchester chairs the Combined Authority and holds strategic powers over transport, housing, skills, economic development, planning, policing and fire services. The role comes with a multi-billion-pound budget and the ability to shape long-term priorities for a region of nearly three million people. Successive mayors have used the post to push for greater devolution, better public transport, more housing and a stronger regional voice in national debates. The office has become one of the most influential metro mayoralties outside London, and the person who wins it will help determine the direction of Greater Manchester through to 2028.
The Day After and Beyond
As counting continued on 31 July, attention turned to turnout, the first-preference totals and whether a second round would be required. The declaration was expected during the afternoon or later if transfers proved necessary. Once the result is confirmed, the new mayor will take office and begin the work of setting budgets, working with the ten local leaders and addressing the practical challenges facing the city region.
This by-election closes one chapter and opens another. For nine years the mayoralty was closely identified with a single political figure. The 2026 contest forced the region to choose a successor under different circumstances and with a wider field of competitors. Housing pressures, transport ambitions, economic inequality between boroughs and questions of community safety will not disappear with the result. They will form the core of the new mayor’s agenda.
Greater Manchester has long presented itself as a laboratory for devolution and regional leadership. The 2026 by-election tested whether that model can transfer smoothly from one leader to the next. The voters have now spoken. The coming months will show how their choice shapes the daily experience of living, working and travelling across the city region.
